Injectable steroids are injected into muscle tissue, not into the veins. They are slowly released from the muscles into the rest of the body, and may be detectable for months after last use. Injectable steroids can be oil-based or water-based. Injectable anabolic steroids which are oil-based have longer half-life than water-based steroids. Both steroid types have much longer half-lives than oral anabolic steroids. And this is proving to be a drawback for injectables as they have high probability of being detected in drug screening since their clearance times tend to be longer than orals. Athletes resolve this problem by using injectable testosterone early in the cycle then switch to orals when approaching the end of the cycle and drug testing is imminent.
It could be argued that aromatization is a non-issue, as an . could always be employed to counter estrogen conversion. This is true, but I believe there is a simpler way to go about it. In my opinion, the ideal pre-contest MPD cycle should consist of a low dose of testosterone propionate (150-200 mg/week), as at least some estrogen is needed to maintain a healthy looking skin tone. This should be combined with 2-3 other anabolics; preferably 1-2 oral anabolics and 1-2 injectables anabolics. Some good examples of orals include: Anavar, Epistane, and Turinabol. As for injectables, most people usually find the following drugs to be compatible: Primo, Boldenone, and Dihydroboldenone (1-testosterone).
